oEvent-based OTP (HOTP)—expires when used or when generating a new OTP

oTime-based OTP (TOTP)—expires within a few seconds (expiry animation displayed in the mobile application) even if not used

Push Authentication

Hard tokens

oHard tokens are the only available authentication option if ESA is used in an offline environment.

OTP received via custom delivery option

FIDO—only one FIDO authenticator can be registered per user



Reliability of SMS delivery

Due to the technical nature of SMS messages, which are typically handled by local operators of telecommunication services, the reliability of SMS delivery to end-user mobile phone cannot be guaranteed by ESET.
